TO ALL WHOM IT MAY CONCERN:

Be it known that I, C. P. HAWLEY, of Mosherville, in the county of Saratoga, and State of New York, have invented a new and useful Improvement in Wagon-Springs; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 represents a side elevation of a wagon provided with my improved spring.

Figure 2 is an inverted plan view of the same.

Similar letters of reference indicate corresponding parts. I

This invention relates to a new manner 'of arranging the springs on all sorts of vehicles, sofas, railroad cars, and for other purposes, and consists in having two frames, made of wood or other suitable material, hinged to lugs projecting from the under side of the wagon-box or other articles, said frames being so arranged that they nearly meet at their inner ends, while their outer ends are hinged to the respective wagon-axles, or to some stationary arrangement not connected with the box. The inner ends of the frames are linked together or otherwise flexibly connected, and are drawn to the under side of the box by means of a spring or springs, of suitable construction. As the box is weighted it bears upon the hinged centres of the frames, and transfers part of the strain to the axles and a part to the spring, by which the inner ends of the frames are drawn or pushed towards the wagon-box. Thus, with but a proportionately small spring, a heavy box or seat can be supported and made elastic. i

A represents a wagon-box. B is the front axle, O is the rear axle, of a wagon. D D are the wheels. E E are two frames, formed of side bars, as shown in fig. 2, that are connected in any suitable manner. Each of these frames is'hinged by a pin or pins, a, to :1. lug or lugs, b,.which project from the under side of the wagon-box, as shown. The position of the lugs under the wagon-box is such that the pins :1 pass about through the centres of the bars E. That portion of each bar E through which the pin a passes is slotted, as shown in fig. 1. The outer end of each .frame E is hinged by means of staples a or other hinges to one of the axles, as shown in fig. 1. The frames E almost touch each other at their inner ends, and are connected by means of links old, or rubber straps, or their equivalents. F is a spring, which is secured to the under side of the wagon-box, and'isconnected with the inner ends of both frames E. When the box A is not weighted, the frames E are inclined, as shown in fig. 1; but when a-weight is placed into the box,the same will depress the centres ofthe frames E, the spring F. offering resistance to such a depression. The more the inner ends of the frames are depressed the nearer will the bearings a come to the axle in the slotted bars E, and thus the bearing is moved more and more towards the axle the heavier is the load.

It will be easily understood that this invention can be applied with equal advantage to' other purposes as well as to vehicles of all classes. The spring F may, instead of being secured to the under side of the wagonbox, be secured upon the bars G which connect the axles B and 0, when it will be below the frames E, and will then push the inner ends of the same to the wagon-box, instead of drawing them towards the same. Spiral, rubber, elliptic, or other springs may be used for this purpose.

I' claim as new, and desire to secure by Letters Patent- 1. The arrangement and combination of the frames E E with the lugs 6, pins a, staples a, links cl, or their respective equivalents, with the spring F, all made and operating substantially as herein shown and described.

2. The slotted hinged frames E, when so arranged that the bearings will bebrought nearer to the axles the heavier the load, as set forth.

C. P. HAWLEY.
